State-of-the-art prosthetic limbs can help people with amputations achieve a natural walking gait, but they don’t give the user full neural control over the limb. Instead, they rely on robotic sensors and controllers that move the limb using predefined gait algorithms.

Using a new type of surgical intervention and neuroprosthetic interface, MIT researchers, in collaboration with colleagues from Brigham and Women’s Hospital, have shown that a natural walking gait is achievable using a prosthetic leg fully driven by the body’s own nervous system. The surgical amputation procedure reconnects muscles in the residual limb, which allows patients to receive “proprioceptive” feedback about where their prosthetic limb is in space.

In a study of seven patients who had this surgery, the MIT team found that they were able to walk faster, avoid obstacles, and climb stairs much more naturally than people with a traditional amputation.

Seeing what’s going on inside a body is never easy.

In a stunning experiment, researchers were able to see through a living mouse’s skin to its internal organs, simply by applying common light-absorbing molecules.

Doctors have long known that inflammation plays a significant role in triggering heart attacks and strokes. Now for the first time, an anti-inflammatory drug is on the market to prevent these cardiovascular events.

“It is a game changer,” says Ian Neeland, MD, Director of Cardiovascular Prevention at University Hospitals Harrington Heart & Vascular Institute.

“We’ve known that low-grade, systemic inflammation is a powerful determinant of recurrent cardiovascular events. Colchicine is the first drug we have on the market for inflammation that reduces this risk,” says Dr. Neeland.

The risk of getting dementia may go up as you get older if you don’t get enough slow-wave sleep. Over-60s are 27 percent more likely to develop dementia if they lose just 1 percent of this deep sleep each year, a 2023 study found.

Slow-wave sleep is the third stage of a human 90-minute sleep cycle, lasting about 20–40 minutes. It’s the most restful stage, where brain waves and heart rate slow and blood pressure drops.

Deep sleep strengthens our muscles, bones, and immune system, and prepares our brains to absorb more information. Recently, research discovered that individuals with Alzheimer’s-related changes in their brain did better on memory tests when they got more slow-wave sleep.

If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour.

Unfortunately, much of this heat simply escapes into the atmosphere. Wouldn’t it be great if we could harness it to produce energy? My research has shown this would indeed be possible. My colleagues and I are discovering ways of capturing and storing body heat for energy generation, using eco-friendly materials.

Can someone smarter than I tell me if this has any implications regarding the Covid vaccine?

Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA to proteins. But only two percent of the human genome actually encodes proteins; the function of the remaining 98% remains largely unknown.

In an incredible feat that redefines biological boundaries, scientists have successfully engineered animal cells capable of photosynthesis.

This breakthrough, led by Professor Sachihiro Matsunaga at the University of Tokyo, could transform medical research and aid in advancing lab-grown meat production.

Photosynthesis, traditionally exclusive to plants, algae, and certain bacteria, is a process that uses sunlight, water, and carbon dioxide to produce oxygen and sugars – essentially “feeding” the organism.

A new study from researchers at Wilmer Eye Institute, Johns Hopkins Medicine explains not only why some patients with wet age-related macular degeneration (or “wet” AMD) fail to have vision improvement with treatment, but also how an experimental drug could be used with existing wet AMD treatments…

Wilmer Eye Institute researchers have found that ‘wet’ macular degeneration patients who don’t respond well to treatment have an increased protein in their eyes and that an experimental drug can help improve vision gains. ›
